Contour Method: Calculating Stress Using Finite Elements |
|||||||||||||||||||
Residual Stress Conferences |
For help with calculations: (26 MB) Johnson, G, 2008, "Residual stress measurements using the contour method," Ph.D. Dissertation, University of Manchester, School of Materials. A very thorough thesis with lots of practical and helpful information on the contour method and then some very good applications including several advances.The Matlab files described in the dissertation and some examples are available here: GJohnsonFiles.zip (3.6Mb). Use of the spline program requires the curve fitting toolbox. (Posted with permission of author)
Now we have the residual stresses that originally existed normal to the plane of the cut! Illustrated here for just a 1-D stress profile, but see Applications for examples of getting a full 2-D stress map.
